9 minute(s) of a 172 minute read


the front lip looks wavy cause i have water on the lens

Then i waxed and De-badged the back except for the STI logo

Getting ready to de-badge 

De-badging complete 

Then i got my tint done. 15% in the back




I then order these things. Cusco Catch can and Hella horns 

And this 

Then I ordered a Tomei Equal length header. Found out that i had about a half an inch exhaust leak where the up-pipe connects to the header and also had a leak at the middle of the header

And then this happened cause i didnt have enough clips put in the front fender connecting to the front lip

Still needs to put this on. I put more clips in and bolted it in a couple places

Got bored one day at work and made a little video. Still needs to make a new video with the new header on but here is my old setup.

Then I ordered a grimmspeed y-pipe intercooler piping kit (Blue) and Tomei turbo inlet pipe. Still waiting for my Tomei type-s fuel regulator to come in..

And also got my new side skirts for Alain at (check them out! Amazing service and can get you just about everything)

Then this showed up 4 days early lol 

Getting ready to install 

Also got my Perrin Cozy put on 

And this was the garbage OBX header that came off. Looks like crap 

And this was the final product  hard to get a decent pic while under the car 

I'm very happy with the final product  sounds cleaner in my opinion

Then I ordered these little things lol

I installed my Cusco catch can and my Password JDM quick release fasteners. 

The catch can was a simple install. Bolt bracket, bolt can to bracket and run the blowback line. 

The blowback line was a bit too long so I cut off the extra and put it on the overflow nipple.

Here is the results 

The JDM fasteners was pretty easy too. Jack the car up took the 2 front tires off, drilled holes and bolted them on.

Here are the results for this

Marking the holes

Drilling the holes 

Bolting them on


Then I got my mounting bracket and wiring harness 

Also my girlfriend bought a new car after she flipped her car. Nothing to fancy but she likes it lol and i like it so its all good.

this is her car that she flipped 

and this is the one we got 

Some photos when i was debadging 

Then I installed my Hella horns. That bracket and harness made everything so much easier

These are the horns on the bracket 

And the Hella horn next to a stock horn

Horns installed 

Also installed my side skirts that day

jacked up!

Old ones next to New ones 

The line of bolts lol


And last weekend i put on my Tomei inlet pipe 

Stock still in 

Stock next to Tomei 


And this is where im sitting as of now. Still waiting for my Grimmspeed Y-pipe kit and needs to go in and get my Tomei Fuel regulator and my DW65c Fuel Pump

Here is my baby to date
